GFpECSetPoint, GFpECSetPointREgular

Sets up the coordinates of a point on an elliptic curve.

Syntax

IppStatus ippsGFpECSetPoint(const IppsGFpElement* pX, const IppsGFpElement* pY, IppsGFpECPoint* pPoint, IppsGFpECState* pEC);

IppStatus ippsGFpECSetPointRegular(const IppsBigNumState* pX, const IppsBigNumState* pY, IppsGFpECPoint* pPoint, IppsGFpECState* pEC);

Include Files

ippcp.h

Parameters

pX, pY

Pointers to the X and Y coordinates of the point on the elliptic curve.

pPoint

Pointer to the IppsGFpECPoint context.

pEC

Pointer to the context of the elliptic curve.

Description

This function sets up the coordinates of a point on the elliptic curve over the finite field.

Return Values

ippStsNoErr

Indicates no error. Any other value indicates an error or warning.

ippStsNullPtrErr

Indicates an error condition if any of the specified pointers is NULL.

ippStsContextMatchErr

Indicates an error condition if any of the specified contexts does not match the operation.

ippStsOutOfRangeErr

Indicates an error if the point coordinates (pX, pY) do not belong to the finite field over which the elliptic curve is initialized.
